Sorry I meant to say 40,000 square meters its 200 meters x 200 meters. Im from central México. So Sandy I have a couple of questions if you dont mind lets say that I was to get lucky and I capture an Aura and that there were monuments in the area and one of the monuments was an owl, now you can only see the owl from one derection so I walk backwards making sure that I can still see the own and now im looking to my right and left to see if I can spot two others monuments in line to make a criscross to the digging spot. So my question is do you have to be able to continue seeing the owl as you walk backwards or is it possible that the criscross spot can be going the oppisite direction or even sideways from the owl? Thats what im not sure. And my other question is that you mention that some treasures are burried 5ft 6" minimum, so even though their deep and have a cover over them or maybe sealed they can still create an Aura at the surface?
